We report results from the NEMO-3 experiment based on an exposure of 1275 days with 661 g of 130Te in the form of enriched and natural tellurium foils. The double B decay rate of 130Te is found to be greater than zero with a significance of 7.7 standard deviations and the half-life is measured to be T2v 1/2 = [7.0 +/- 0.9(stat) +/- 1.1 (syst)] x 10{sup 20} yr. This represents the most precise measurement of this half-life yet published and the first real-time observation of this decay.
